In oxy-fuel heating, which gas is commonly preferred?

• A. Oxygen
• B. Propane
• C. Hydrogen
• D. Nitrogen

Answer: (B)

In oxy-fuel heating, you mix a fuel gas with oxygen to create a flame used for heating, brazing, and similar tasks. Propane is commonly preferred because it’s practical and economical: it’s easy to store and handle, widely available in shop gas cylinders, and provides a reliable, controllable flame with a suitable temperature for most heating needs. It strikes a good balance between heat output and safety, without the specialized hazards and higher cost associated with acetylene. Oxygen is the oxidizer, not the fuel, so it isn’t chosen as the gas to burn. Hydrogen can be used in some setups but is less common due to handling complexity and safety concerns. Nitrogen is inert and used mainly as a shielding gas or for other non-heating purposes, not as the fuel in oxy-fuel heating.
